Infrastructure management vendor Avocent has agreed to buy LANDesk, which makes desktop management products, for US$416 million, the companies said on Thursday.

LANDesk offers software products, including tools for desktop management and security, and has built up partnerships with several big PC makers including Lenovo, since it was spun out of Intel in 2002.

The LANDesk acquisition follows the Avocent's purchase of Cyclades earlier this year. Cyclades specialises in Linux-based management tools.
